Abstract (en)
Planar inverted antenna arrangement (PIFA) for a portable communication device, said antenna arrangement comprising: a first upper L-shaped antenna patch (12) to be connected to a ground plane (15) having ground potential (V1), and a second lower L-shaped transmission antenna patch (14) to be connected to a feeding potential (V2), said antenna patches (12, 14) being arranged adjacent to each other separated by a first gap (17a) forming a capacitance like structure to provide a frequency dependent capacitive feeding, wherein said second lower antenna patch (14) is separated by a second gap (17b) to the ground plane (15), which second gap (17b) comprises dielectric material.
